build: accommodate newer bootstrap from gnulib
* bootstrap.conf (gnulib_tool_option_extras): Add both --symlink and --makefile-name=gnulib.mk. Also remove now-obsolete $bt/ prefix. * bootstrap: Update from gnulib. * tests/init.sh: Update from gnulib. * lib/Makefile.am: Initialize numerous variables, so that generated code in gnulib.mk may use += to append to them.
